Title: Driving force transmission device
Inventor: INOUE MASAHIRO
IPC: F16D31/06
Filed: 1993-07-21
Abstract: PURPOSE:To reduce the power consumption in a driving coil and enhance the reliability of operation and manufacture a spool so favorably in terms of efficiency. CONSTITUTION:A second spring 67, making a second spool 63 return to the side of an opening end 61b of a spool chamber 61, is spread over in space between a spring supporting part 62a of a first spool 62 and a stepped part of the second spool 63. With this constitution, since energizing force of the second spring 67 can be damped in a state that the first spool 62 is slidden to the side of a blocking end 61a of the spool chamber 61, magnetic force for sliding the second spool 63 to the side of the blocking end 61a can be weakened. Therefore, the power consumption in a driving coil 69 can be reduced. Such a fact that the second spool is shifted together with the first spool by a spike current is preventable by the second spring 67. In addition, as the second spool is formable into a cylindrical form, this spool can be efficiently finished by means of through feed system polishing.
